DIN The AD7738 features a powerful digital interface with configuration flexibility. However, this means that the user may have to write tens of bytes of information to correctly configure the ADC.

Typically, users write a byte and then read it back to confirm that it has been correctly received. When reading conversions, it is common for users to read the data register three times and compare the three results to validate the data.
